I can’t understand this either because I tried to buy at 3.40 approx last Saturday and could only get a seat in the main stand in the lower seats in line with the goal line. Happy enough with the seat but someone put up a photo of the main stand after the game was underway and you could clearly see how many seats were empty, I know about the red zone ok. It was clear that my usual seat and all around it was mostly empty. This should not be the case and needs sorted.
